Would make a great backup, second or slave strobe for somebody- I am downsizing and dont need the number of strobes like this that I have anymore- quite a few body scratches on it from lots of use- all cosmetic in nature, strobe was never flooded. Takes 8 AA batteries and has a guide number of 22 (if I remember correctly)- a web search ought to get you any background info you need. comes with diffuser, o-ring for both battery hatch and cable connection port and the arm connector screw and front end diffuser. Slave capabilities as well as Full, and 1/2 power settings (TTL if you still have a film camera). $125 + shipping. US sales preferred for now.
